Abstract
A marking device for a shorthand machine selectively marks the margins of the paper tape output of the shorthand machine to denote a portion of the shorthand notes for ready reference. The activating keys for the device are located in close proximity with the machine keyboard, whereby the operator may activate the device with minimal interruption of the recording process. Disposable marking instruments may be employed in the device. Incorporation of the device in the machine cover preserves the first planar surface of the cover and further, facilitates storage of the device when not in use.
Claims14
A marking device for a shorthand machine comprising:
- (a) a housing, said housing having
- (i) a substantially flat, rectangular base plate having a longitudinal channel extending the length of the base plate,
- (ii) a substantially flat, rectangular top plate complementary to the base plate and secured to the base plate, and
- (iii) means maintaining said top plate and said base plate in spaced-apart relationship;
- (b) an elongate key having a forward and rearward end;
- (c) means for mounting said key for substantially longitudinal movement within said channel between a retracted and an advanced position;
- (d) biasing means continuously urging the key toward its retracted position;
- (e) means for removably mounting said housing on the shorthand machine;
- (f) a marking instrument mounted adjacent the forward end of the key for movement with the key between the retracted and advanced positions;
- and
- (g) a finger-engagement means at the rearward end of said key to facilitate manual longitudinal movement of said key between the retracted and advanced positions.
A marking device for selectively marking the margin of a paper tape in a shorthand machine of the type having a platen for advancing the paper tape and a keyboard for operating the machine so that information may be recorded by the machine on the paper tape being advanced by the platen, said marking device comprising:
- (a) a housing, said housing having
- (i) a substantially flat, rectangular base plate having a longitudinal channel extending the length of the base plate,
- (ii) a substantially flat, rectangular top plate complementary to the base plate and secured to the base plate, and
- (iii) means maintaining said top plate and said base plate in spaced-apart relationship;
- (b) an elongate key having a forward and rearward end;
- (c) means for mounting said key for longitudinal movement within said channel between a retracted and an advanced position;
- (d) biasing means continuously urging the key toward its retracted position;
- (e) means for removably mounting said housing on the shorthand machine intermediate the platen and the keyboard with the rearward end of said key disposed adjacent the keyboard when said key is in its retracted position;
- (f) a marking instrument mounted adjacent the forward end of the key for movement with the key whereby the marking instrument will be moved into contact with the paper tape when the key is moved to its advanced position for applying a mark on the paper tape;
- and
- (g) a finger-engagement means at the rearward end of said key to facilitate manual longitudinal movement of said key between the retracted and advanced positions.
A disposable cartridge for use as a marking instrument in a marking device for a shorthand machine of the type having a platen for advancing a paper tape, the marking device having an elongated operating key defining a forward cavity, the disposable cartridge comprising a "U"-shaped holder, the base of the "U" comprising a live hinge for facilitating insertion of the disposable cartridge into and removal of the disposable cartridge from the forward cavity of the elongated operating key, and a marking element mounted in said holder and positioned for striking the paper tape carried by the platen upon advancement of the key.
A marking device for a shorthand machine comprising:
- a. a housing, said housing having
- (i) a substantially flat, first plate having a longitudinal channel extending the length of the first plate,
- (ii) a substantially flat, second plate complementary to the first plate and secured to the first plate, said second plate constituting a cover for said channel, and
- (iii) means maintaining said first plate and said second plate in spaced-apart relationship;
- b. an elongate key having a forward and rearward end;
- c. means for mounting said key for substantially longitudinal movement within said channel between a retracted and an advanced position;
- d. biasing means continuously urging the key toward its retracted position;
- e. means for removably mounting said housing on the shorthand machine;
- f. a marking instrument mounted adjacent the forward end of the key for movement with the key between the retracted and advanced positions;
- and
- g. a finger-engagement means at the rearward end of said key to facilitate manual longitudinal movement of said key between the retracted and advanced positions.
